I would GREATLY apriciate if any math-wiz out there could take the time to check my work.!
You can even just look at the conclusions! or just check one or two. Please?

1. conclusions:
principal(P)= $600
Rate of intrest(R)= 5%
Time(T)= 4 year
interest(I)= $ 120
balance(B)= $720

formulas/work:
I = RxTxP
I = .O5 x 4 x 600
I = $120

2. Conclusions:
P= $980
R= 6 %
T= 6 months
I = $29.40
B = $1009.40

formulas/ work
I = PxRxT
I = 980 x.O6 x .5
I = $29.40

3. Conclusions:
P= $1620
R=8%
T=3 Months
I = $32.40
B = $1652.40

formulas/ work:
P = I / RxT
P = 32.40 / .O8 x .25
P = 32.40 / .O2
P = $1620

4. Conclusions:
P = $1400
R = 2.8%
T = 6years
I = $235.20
B = $1635

Formulas/ work:
I = PxRxT
I = 1400 x .O28 x 6
I = $ 235.20

** Please check, I spent all that time writing all that stuff because I really need to get a 100 on this I am failing math and this is the only thing to pull up my grade and I NEED TO DO MY BEST ON IT. Remeber, you can just look at the conclusions if you want too! Please !!! <3**
